This invention relates to a sash window, the

lower sash of which lies in the closing positionv in the same plane with the upper sash. The invention consists in that the lower sash is guided 6 by means of lateral'pin-bars of U-shaped cross section, which are iixed from the lower edge of the lower sash up to the top edge of the same on i elements hingedly mounted in and adapted to be turned down out of the window frame and eX- 10 tend as separate stationary connecting bars up to in front of the upper sash or the front guide bars of the same. Thus on the one hand the lower sash, after the turning down of the U- shaped guide bars can be kfreely turned over kand 1I on the other hand if well guided it can be shifted upwards in front of the upper sash.

An embodiment of the invention is illustrated in which:

Fig. 2 is a longitudinal section of Fig. l.

Fig. 3 is a section on line 3-3 of Fig. l. a is the lower sash and b the upper sash. The upper sash b is `guided vertically snif-table on the 25 and on the upper end by lateral shiftablepins d in grooves e in the side parts of the window frame. Corresponding to the front guide bars g of the window frame for the upper sash guide bars h adapted to be turned down out of the windowv frame are arranged in front of the lower sash a. These guide bars I1, are adaptedto be secured in,- the inoperative position by means of latches J. Onv the inner edge of the guide bars h metal bars i of U-shaped cross section are arranged, which extend upwards as separate stationary bars.A Pins 1c projecting from the lower sash lower edge by laterally arranged stationary pins cv can be shifted upwardly to in front of the upper sash b as the pins k .of the lower sash a and guided in the curved U-shaped bars i to in front of the guide bars g of the upper sash'. The upper sash b can then be moved downwards in being reliably guided by means of the pins c and. d in the grooves e in the side parts oi'v the window frame. In its lowered position the upper sash b can be turned over, the pins c serving as pivots. Ii the guide bars h are turned over from out of the window frame, after the latches f have been pulled back, the lower sash .a can be freely turned over.

In order to ensure the lower sash a in the posi-` tion in which itsV upper edge bearsagainst the guide h, or against the U-shaped metal bars i fixed thereon i. e;r to prevent it from swinging back, hooks may be hingedly xed on the upper edge of the lower sasha adapted to engage in the U-shaped metal bars 75 I claim: Y

A sash window the upper and lower sashes of which lie in the same plane when the window is closed, comprising in combination with the uprights of the window frame the Vupper sash, vertically shiftable in said frame and the lower sash, guide pieces hingedly connected at their lower end to the lower end of said uprights and extending to the top of said llower sash, guide barsv Aof U-shaped cross section mounted on and extending to the upper edge of said guide pieces, lateral pins onl the lower end of said lower sash engaging in said U-bars, and rigid extensions of .said U-bars on the upper portion of said uprights HEINR.
